Time Attack amongst Street, Modified, and Super Modified classes are invited to participate in a five lap sprint race. Only vehicles with the necessary safety equipment are allowed to compete. One race with mixed classes is conducted in a traditional wheel-to-wheel format, with the grid arranged with the fastest cars up front and slowest in back. The field takes the green under a rolling start, and the winner is the first to cross the finish line after five laps. Passing is allowed at any time after the green flag. Points are awarded to the drivers based on finishing position. As of 2011 Super Sessions were no longer a part of Redline Time Attack competitions.
